Good question.
No, such a facility is not available directly, however. A domain's configuration is generally independent of actual running server's/cluster's configuration. What you can best do is to identify those things in your JVM configuration that can be tokenized and define the values of those tokens at a domain level. The idea is manifested by using what we call "system-properties" (an unfortunate name as it conflicts with Java system properties) and is denoted as a <system-property> element in domain.xml. For example, you could define something like this:
<system-property name="MaxHeapSize" value="1024m"/>
and refer to it from a cluster's configuration (e.g. in <cluster1-config> as:
<java-config ...>
<jvm-options> ${MaxHeapSize} </jvm-options>
...
</java-config>
Thus, when you change the value of the system-property to say 2048m, all the clusters would
start asking for 2G as the maximum heap size.
Hope this helps.

PS - look at: [b]asadmin create-system-properties[/b] command.
